CHRISTOPH SCHNEIDER, OF BOULDER, COLORADO.

DOOR-STOP.

To all whom it may concern:

Be it known that I, CHRISTOPH SCHNEI- nnn, a citizen of the United States, residing at Boulder, in the county of Boulder and State of Colorado, have invented certain new and useful Improvements in Door- Stops; and I do declare the following to be a full. clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in door stops. my object being to provide an equipment for the doors of buildings, whereby the doors when open may be held in any desired position and are not liable to be accidentally closed or swung more widely open. by the wind or other agency. h

My further object is to equip doors with a device of the character aforesaid, in such amanner that the said device will be entirely concealed wit-hin the j amb of the door; and to this end, I form a mortise or recess within the door amb and place within the said recess a spring-actuated rod, vertically movable in suitable guides. The lower or stop extremity of the rod is equipped with a yielding plug preferably composed of rubber to prevent the marring` of the floor or inyury to carpets or rugs. The door is also provided with a springactuated pawl adapted to support the stop in the raised position or in a position whereby its lower extremity shall be raised from the floor or other surface.

Having briefly outlined my improved device, I, will proceed to describe the same in detail reference being made to the accompanying drawing in which is illustrated an embodiment thereof.

In this drawing, Figure 1 is a sectional view of the door amb showing my improved door stop in place, the same being raised to prevent it from coming in Contact with the floor or other surface above which the door swings. Fig. 2 is a face view of the door j amb showing the device lowered to form a stop. In Fig. 2 thel door occupies a position at right angles to Fig. 1. Fig. 3 is a view similar to Fig. 1 but viewed from the opposite side of the door, the door stop being lowered to engage the floor or other surface.

Specification of Letters Patent.

Application filed August 16, 1907.

Patented Nov. 10, 1908.

Serial No. 388,748.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a door in the jamb of which is formed a mortise 6. This mortise is closed on the outside or face of the jamb by a plate 7 which is held in place by screws 8. This plate is equipped with horizontally disposed apertured guides 9 which protrude into the mortise. Passing through the openings in these guides is a rod 10 whose lower extremity is equipped with a shoe 11. As shown in the drawing the upper extremity of this shoe is provided with a socket into which the lower extremity of the rod is threaded. This shoe is also formed hollow and open at the bottom to receive a yielding stop 12 preferably formed of indial rubber. This stop may be held in place by means of a rivet 13 or other suit able fastening device. Between one of the guides 9 and a stop collar 14k attached to the rod, is a coil spring 15 which is under sufficient tension, to hold the stop 12 against the floor 1G or other surface with sufficient force to hold the door in the desired position of opening adjustment under ordinary circumstances, If great force, however, is applied to the door the stop will allow it to move without breaking. This stop is only intended to cause the door to resist ordinary strains or forces.

Pivotally mounted on a lug 17 formed on the inner surface of the face plate 7, is a locking pawl 18 whose lower extremity is equipped with a button 19 protruding through an opening 2O formed in the face plate. This button extremity of the pawl is normally held in its outer position by means of a leaf spring 21. The upper extremity of this dog is adapted to engage a notch or recess 22 formed in the rod 10, when the latter is raised to cause the stop 12 to clear the iioor. When it is desired to release the stop, it is only necessary to press inwardly on the button extremity 19 of the pawl, in which event its opposite extremity is disengaged from the recess 22, allowing the rod to move downwardly under the influence of the spring 16, whereby the stop is caused to engage the Hoor with sutlicient force to accomplish the object of the invention.

To the upper extremity of the rod 7, is pivotally connected a small plate 23 which normally occupies a position concealed within the mortise 6. The face plate, however,

is provided with an opening 24E to allow the plate 23 to be swung outwardly to the position shown in full lines in` Figs. 2 and 3. This plate when swung to the position 5 shown in the last named views, allows'the operator to readily lift the rod 10, whereby the latter is raised to cause the stop to clear the floor and at the same time Vallow the pawl 1S to engage the recess of the rod to lo support the latter in the desired position.

Having thus described my invention, what l claim is:

l. The combination with a door provided j@ with a mortise jamb, of a face plate applied Y to the lower jamb and equipped with horizontally disposed guide plates which protrude into the inoi'tise, a rod slidably mounted in said guide plates, a spring under ten f sion to in ove said rod downwardly,the lower extremity or' the rod being provided with a yielding stop, and a spring actuated pawl mounted 'on the face plate and exposed through an opening formed in the latter' for joperating purposes, said pawl supporting the rod in position to disengage its stop from the-floor, substantially as described.

2. The combination with a door provided with a mortise formed in its jamb, aA face plate applied to the jamb of the door to close said mortise on the outside, the said .a button normally entering an opening formed in the said face plate, making the pawl accessible for the purpose of releasing the rod, substantially as described.

3. The combination with a doorgoffguides mounted thereon, a vertically disposed spring-actuated rod movable in the guides, the lower extremity of the rod being provided with a yielding stop, andits upper extremity with a lifting device, and suitablel means operated by a button normally entering an opening termed in the face plate for supporting the rod in position to raiseV the stopper above the floor or other surface, substantially as described. i

ln testimony whereofA l atlix my signature in presence ot' two witnesses.
